  • Page 7: Introduction

    This manual provides instruction for installing and operating the General Monitors Model 2180A Single Channel Control Module for Hydrogen Sulfide Gas Applications. While the 2180A system is easy to install and operate, this manual should be read in full, and the information contained herein understood, before attempting to place the system in service.

  • Page 8: Customer Support

    Model 2180A General Monitors’ gas detection systems are primarily safety devices for the protection of personnel and facilities and must be “always ready”. With proper installation, calibration, and maintenance, the system provides continuous monitoring of hazardous areas. The user must assume all liability for misuse of General Monitors’...

  • Page 9: Before Installation

    Please check the individual manuals for details about wiring, set up and operation of these two units. CAUTION: The Model 2180A Controller is easy to install and operate. However, one should fully read and understand this manual before attempting to place the system in service.

    The controller operating temperature range is 0°C to 60°C (32°F to 140°F). 2.2 Power Connections The Model 2180A operates on a nominal line voltage of 117 VAC, 50-60 Hz., 220 VAC operation is an available option. NOTE: To eliminate accidental shutdown, GMI does not provide a power ON-OFF switch.

  • Page 13: Battery Backup

    (ampere-hour capacity) is dictated by the length of time power outages may last. A Model 2180A Controller requires approximately 2 ampere (peak) at 24 VDC. General Monitors recommends that a lead-acid type battery be used. This type of battery can be expected to last for several years with minimum maintenance.

    3. Connect the cable so that the terminal color at the sensor housing matches the terminal color at the controller. General Monitors’ sensor leads are color coded, and should be connected to the rear terminal connector as shown in the following...

  • Page 17: Alarm Wiring Connections

    2.8 Alarm Wiring Connections The Model 2180A alarm relays may be operated as normally de-energized or normally energized, and latching or non-latching. The Low and High alarm contacts for customer use are DPDT (double pole, double throw), and are rated 4 amps at 115 VAC, resistive.

  • Page 18: Figure 3: Protection Circuit For Relay Contacts

    Model 2180A CAUTION: Inductive loads, such as bells, buzzers, relays contactors solenoid valves, etc., connected to the High alarm, Low alarm, and Fault alarm relays must be clamped down as shown in the diagrams below. Unclamped inductive loads can generate voltage spikes in excess of 1000 volts. Spikes of this magnitude will cause false alarms and possible damage.

  • Page 21: Start Up And Operation

    3.1 Types of User Interfaces User interfaces are provided so that the operator may interpret and direct the Model 2180A in the performance of its various functions. User interfaces consist of a digital display, status indicators, a mode button, and a reset button.

  • Page 22: Initial Application Of Power

    Model 2180A • The status indicators provide the user with an indication of the current mode of operation: HIGH (high alarm), LOW (low alarm), FAULT, SETUP (setup and setup check modes), and CAL (calibration or calibration check modes). • Mode button provides the user access to the Calibration, Calibration Check, Setup and Setup Check modes.

  • Page 23: Analog Output

    General Monitors offers ampoules with breaker bottles as a method of reliably introducing calibration gas to the Model 2180A. The ampoule is placed inside the breaker bottle into the breaker slot, and the breaker bottle is placed over the sensor. The ampoule should contain 50% FS of H S of the sensor range.

    Model 2180A 3. Allow the sensor to see the gas for 1 to 2 minutes. NOTE: Do not store the cylinder with the regulator fully engaged in the cylinder valve. 3.6 Calibration Check Mode This procedure is used to periodically check the response of an installed system to a known concentration of H S gas that is at least 50% of the full-scale reading.

  • Page 26: Aborting Calibration

    Model 2180A To Calibrate the Model 2180A: 1. Make sure the sensor is seeing clean air. 2. Enter the Calibration mode by following the same procedure for entering Calibration Check mode. Continue to press and hold the Mode button until the CAL LED becomes steady, approximately fifteen seconds.
